deciphering GE tube date codes.........

Get them now or miss out! This tube has an incredibly clear tone that works well in both hi-fi and guitar amp applications. They are identical internally, carry the same factory code markings, and sound the same. Very hard to find these today, especially in a closely matched pair! Some of the boxes may be ragged or missing, but the tubes are tested and guaranteed operational. No one else has these, very limited stock, you snooze you lose! Very fine tube, in great demand, especially this smoothplate version. Top of the line audio double triode tubes manufactured. All are the real deal, with the diamond mark in the bottom glass. These are all the older long plate version that is so difficult to find today.

The blackplates and most tubes made for organs are very quiet. These sound like the triple mica versions and you pocket the savings! Our tubes are carefully screened for fakes when we obtain them, and are guaranteed genuine. Al Also, is it labeled Realistic Radio Shack brand name?. All in all, it sounds like a totally different system. Just in stock are some nice ones aftermarket screened for use in Marshall and Mesa amps. For most uses, Gm matching is fine.

Hickok tested, and then ear tested in a preamp! These are extremely high demand vintage tubes, so I have these listed on their own page, as my stock changes rapidly. Until 1945 that was the original Ken-Rad factory. Grab some now before the secret is out! If there is no Philips code, and it says Made in Gt. Things that make you go hmmmm. I'm leaning toward it possibly being Japanese-made, on the basis of the seams.

12AX7 Tubes in Stock

Add to this the quiet background, and incredible 3-D soundstage these tubes create, make these about the best longplates ever made! Made for medical and hospital equipment, these rare tubes will cure your sonic ills and make your system sound better than ever! Nothing like these are likely to ever be made again. The Raytheon and Westinghouse versions of these tubes are probably as rare as the Genalex and 803S Telefunken tubes. New Old Stock, made in Holland, in original box and whitebox. Fair to excellent labels on those with labels. We use repurposed and recycled packing materials. Grab them if you can find them.

GE long plate 12AX7 differences.

ge 188-5 tube

Please consider the photos to be part of the description, and examine them carefully before bidding. Since virtually all of these were meant for critical test, aircraft, and hospital applications, they are all virtually guaranteed to be low noise and low microphonics. I could ask one of my fellow co-workers that still works at Cain if he can produce a code list - not likely after all the company has been through. This list is organized now by each vintage tube manufacturer. These have become incredibly hard to find especially in pairs in just the last year.

That Tube is worth double what I paid for it Brent! These are all Telefunken labeled, an all have the blue painted tips indicating extensive screening for use in medical equipment. New Old Stock in white box. You know it's always a gamble when you buy tubes online but I got a feeling you guys know what the hell you're doing and I'll be talking to you guys soon. We do not specialize in Electron Tubes and occasionally acquire them with groups of lamps. Please tell us what differences you heard between the ones you like and the later version. We have a few hand selected pairs with excellent labels. Wow, best investment I have made in a long time! Just goes to show how crap new tubes are.

GE 12AT7 RU 188

Magnificent old Mullard vintage tubes with Mullard labels, all 1960s stock, and some say these sound better than the older versions. These are very hard to find, get 'em while you can! As soon as I installed it my preamp went dead silent , so silent that I thought it was off. I'd held it up to a 300-watt halogen lamp in an effort to see if there was a code. These are the early Holland types, long plate version with the rare foil strip D-getter. Holland made orange globe logo tubes. Out of production since the 1970s, there are very difficult to find anywhere, but worth the search! Some can hold the opinion that two rectifiers that supply equal voltage I have 5V4 and gz34 that supply same amount that have drastically different effects on the way an amp feels and responds. These tubes are currently soaring in value as stocks of them vanish.

These are fast disappearing from the vintage market, so grab some now! Some are other labels such as Mazda, some are blank organ repair stock, but are Ei made tubes with the Yugoslavia factory date codes on the glass. These have that sweet Mullard sound at a lower price! With the new tube, the front edge of every strike is distinct, bringing the sense of pace and rhythm to new heights. These tubes are dead quiet, ruler flat, laboratory grade beauties that will knock your socks off! Suitable for industrial and airborne electronic equipment subject to severe vibration and shock, these 7 pin glass tubes come with gray plates and top getters. These pairs have been tested in my amplifier for noise, stereo balance and image, and microphonics, then reconfirmed the match on the tube tester. These 1950s era longplates have been screened for low noise use in Wurlitzer and other brands of organs, and to exacting specs for various manufacturers of amplifiers. A very elusive tube to find, especially these very scarce longplate versions. From the estate of an avid hobbyist who enjoyed this equipment without incident.
